FoFa MCP Server

Overview

The FoFa MCP Server is a specialized gateway that exposes the full breadth of the FoFa API to AI assistants following the Model Context Protocol. By translating standard MCP calls into authenticated requests against FoFa’s vast internet‑wide asset database, it lets developers and researchers tap into real‑time information about devices, services, and network footprints without leaving their AI workflow. This solves the common pain point of having to manually manage API keys, construct HTTP queries, and parse JSON responses—all tasks that can interrupt the conversational flow of an AI assistant.

At its core, the server offers two primary tools: and . The search tool accepts a FoFa query string (e.g., ), pagination parameters, and a field selector to fine‑tune the payload. The assistant can therefore ask for “the top 10 web servers hosting ” and receive a concise, structured list of IPs, ports, and titles. The user‑info tool retrieves account details such as usage limits, remaining quota, and email address, enabling the assistant to adapt its behavior when approaching API caps or prompting for key renewal.

Key capabilities include:

• Dynamic querying of the FoFa database, allowing real‑time reconnaissance and asset discovery directly within a conversational interface.
• Pagination support so large result sets can be fetched incrementally, keeping responses lightweight and responsive.
• Field selection to reduce payload size and focus on relevant data, which is essential for downstream processing or visualization.
• Built‑in authentication through environment variables ( and ), ensuring secure, stateless access that integrates seamlessly with existing AI deployment pipelines.

Real‑world scenarios that benefit from this MCP server are plentiful. Security analysts can have an AI assistant perform live sweeps of a target domain, automatically flagging exposed services. Compliance teams might query for all devices that expose deprecated protocols within an organization’s network, while researchers can gather large datasets for trend analysis without writing custom wrappers. Because the server adheres strictly to MCP, it plugs into any MCP‑compatible assistant—Claude Desktop, Claude.app, or future tools—without requiring custom connectors.

Unique advantages of the FoFa MCP Server stem from its tight coupling with FoFa’s search syntax and rich metadata. The ability to specify arbitrary query strings means developers can craft complex, domain‑specific searches on the fly. Coupled with the assistant’s natural language understanding, users can ask high‑level questions (“Find all IoT devices with open Telnet”) and receive precise, actionable results. This blend of flexibility, security, and minimal friction makes the FoFa MCP Server an invaluable component for any AI‑driven network intelligence workflow.
